A storage device system includes an information processing device, a first storage device equipped with a first storage volume, and a second storage device equipped with a second storage volume. The information processing device and the first storage device are communicatively connected to one another. Also, the first storage device and the second storage device are communicatively connected to one another. The information processing device is equipped with a first write request section that requests to write data in the first storage device according to a first communications protocol, and a second write request section that requests to write data in the second storage device according to a second communications protocol. The information processing device creates first data including a first instruction to be executed in the second storage device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A storage device system coupled to an information processing device, the storage device system comprising: a first storage device communicatively connected to the information processing device and managing at least one logical storage volume and a virtual volume in the first storage device, the at least one logical storage volume and the virtual volume are provided to the information processing device, the at least one logical storage volume in the first storage device including a first logical storage volume; and second storage devices communicatively connected to the first storage device and managing at least one logical storage volume in the second storage devices including a second logical storage volume, wherein the virtual volume of the first storage device is related to the second logical storage volume, wherein when the first storage device receives a first command directed to the first logical storage volume in the first storage device from the information processing device, the first storage device stores first data related to the first command in the first logical storage volume and executes the first command using the first data; wherein when first storage device receives a second command directed to the virtual volume in the first storage device from the information processing device, the first storage device transfer the second command and a second data related to the second command to the second logical storage volume in the second device request based on a relationship between the virtual volume and the second logical storage volume, the second storage device stores the second data in the second logical storage volume in response to receiving the second data and executes the second command using the second data.
2. A storage device system according to claim 1 , wherein the first logical storage volume and the second logical storage volume are command devices.
3. A storage device system according to claim 1 , wherein a third logical storage volume included in the at least one logical storage volume in the first storage device configures a remote copy pair with a fourth logical storage volume included in the at least one logical storage volume in the second storage device.
4. A storage device system according to claim 1 , wherein the first storage device is configured to receive both a command directed to the first logical storage volume and a command directed to another logical storage volume included in the at least one logical storage volume in the first storage device according to a first interface protocol.
5. A storage device system according to claim 3 , wherein the second command sent from the information processing device is used to request to obtain the processing status of a copy operation between the first logical storage volume and the fourth logical storage volume.
6. A storage device system according to claim 1 , wherein, in response to receiving the first command, the first storage device is configured to reply to the information processing device via the first logical storage volume.
7. A storage device system according to claim 1 , wherein, in response to receiving the second command, the second storage device is configured to reply to the information processing device via the second logical storage volume.
